If you often find you want to go back more than the default segmentation undo history and you have enough memory in your computer to store more states then [you can increase the maximum number of undo states](https://discourse.slicer.org/t/segment-editor-undo-queue-length/14766).

However, it might be better to just save your work more frequently. You can easily save independent copies of the full scene by clicking on the package icon in Save data window; or you can quickly save just the modified nodes by saving using the default options.
